Description
Given $2n$ participants, each of participant ranks the others in strict order of preference. A matching is a set of $n$ disjoint pairs of participants. A matching $M$ in an instance of SRP is stable if there are no two participants $x$ and $y$, each of whom prefers the other to their partner in $M$. Such a pair is said to block $M$, or to be a blocking pair with respect to $M$.
